To cultivate particular government recommendations, addiitional information will become necessary for the environment choices and you may household variety size of turkeys at its northern range periphery. The initial objective of your investigation was to estimate the fresh new suggest seasonal and you can annual household diversity size of girls turkeys at species’ north range border. We hypothesized one family variety proportions will be greatest on spring season while females are looking for good nesting web site, in addition to smallest regarding winter months and summer. I and hypothesized you to definitely family assortment size within species’ north variety is bigger than those people reported from the south due to shorter dining availability and you may environment top quality. The second mission of our study would be to take a look at seasonal environment possibilities by the people wild turkeys. We reviewed habitat possibilities in an excellent hierarchical manner, playing with Johnson’s (1980) second and 3rd orders away from choices during all the four annual season. We hypothesized you to definitely environment possibilities do changes amongst the year, with turkeys primarily interested in deciduous and you will combined woods, however, in search of open habitat if you find yourself brood-rearing during the summer. All of our final objective were to assess if or not extra restaurants influenced nuts poultry habitat selection. We hypothesized you to north crazy turkeys need supplemental dinner throughout the winter; therefore, we forecast one girls is found next to extra dinner offer regarding bird feeders and animals functions throughout the fall and you will wintertime.

Data urban area

We studied wild turkey ecology away from towards the North Bruce Peninsula, based in Ontario, Canada (Fig. 1). The brand new Bruce Peninsula includes a mix of homes defense sizes, into the prominent safety becoming coniferous forest, combined forest, industries, and deciduous forest (Table step one). Within outlying community brand new prominent marketplace is agriculture and you may tourism. Area of the kind of farming is quick-size meats farming, and lots of visitors go to in the summertime due to a few national parks in the area.

Trapping and dealing with wild turkeys

For the wintertime, turkeys congregate from inside the higher flocks, making it possible to trap multiple wild birds at the same time. We trapped turkeys from in the five urban centers along the analysis city. Turkeys were baited which have corn and you may captured using a rocket online (Grubb 1988). Lure stacks were created in sphere next to in which turkeys were roosting. Immediately after turkeys was indeed trapped, these were taken from the online and you will put into transfer boxes to own holding. Most of the turkeys had been canned on site immediately following capturing. Whenever retrieving a poultry from the container, their ft was in fact covered and a sock is put-on their head. Animal care and attention acceptance is actually provided of the Trent University’s Animal Care Panel (protocol zero. 22238).

I grabbed 53 turkeys, in addition to 47 people and you may six people. We failed to lay transmitters into the a few female due to feather losings on the backs. We match 45 women turkeys having possibly a good 73-grams very-high-frequency (VHF) transmitter (design A1540 Cutting-edge Telemetry Solutions, Isanti, Minnesota) otherwise an enthusiastic 85-grams small global positioning system unit (GPS) sender (model G1H 261A Sirtrack, Havelock Northern, Brand new Zealand). Thirty seven of your females turkeys had been people and you will 7 was basically juveniles.

Transmitters was affixed using a great back pack design use made from treat cord (Norman et al. 1997). The fresh new micro GPS transmitters was basically changed in advance of implementation by the attaching neoprene toward underside of each and every equipment to quit chaffing (Guthrie et al. 2011). To get rid of water damage and mold we secured the vent with a water-resistant silicone sealer and you can a small remove away from vinyl recording (Guthrie mais aussi al. 2011). One another type of transmitters considered below advised maximum away from 3% of mature lady lbs (Millsp). To own character intentions per poultry is installing which have a designated aluminium butt-stop toes band. We also grabbed bloodstream trials out-of for every single bird making numerous morphological measurements (amount of tarsus, wing, mustache and you will tail).
